Abrégé

A storage tank includes a floor, a roof, a sidewall extending between the floor and the roof, an access hatch provided on the roof and having a base, a lid pivotably coupled to the base, and a latch configured to secure the lid to the base in a closed position, and a system for remotely opening and closing the access hatch. The system includes an elongate arm having a proximal end operatively coupled to the lid, a pull cable attached to a distal end of the elongate arm and extending toward a ground adjacent the storage tank, and a latching cable attached to the latch and extending toward the ground adjacent the storage tank, wherein pulling on the latching cable when the lid is in the closed position actuates the latch to secure the lid to the base in the closed position.

Abrégé

A system for remotely opening an access hatch of storage tank includes an elongate arm having a proximal end configured to be operatively coupled to a lid of the access hatch and a distal end extendable past an outer perimeter of the storage tank, and a pull cable attached to the arm at the distal end and being extendable toward a ground surrounding the storage tank. Pulling on the pull cable releases a latch that secures the lid to a base of the access hatch and allows the lid to pivot from a closed position to an open position.
